Fortescue (ASX:FMG) Accelerates Real Zero With 690MW Solar Farm: Is FMG a Buy?

Fortescue’s solar push adds to its green mining story

Fortescue (ASX:FMG) is in the spotlight today after two announcements landed at once: a major board change and a big step forward in its green energy plans. Elizabeth Gaines, a familiar face who has helped shape the company for more than 13 years, is stepping down as executive director on 30 June.

At the same time, Fortescue has started building a 690 megawatt solar farm, its largest yet. For investors, the question is whether these moves strengthen the investment case or simply add noise. In our view, neither changes the core story much, because FMG still lives and dies by the iron ore price.

Fortescue Board Reshuffle: Gaines Out, Kaag In

Gaines joined the Fortescue board in 2013 as its first female director, served as chief financial officer, then ran the company as CEO from 2018 to 2022. She has also been the public face of Fortescue’s “Real Zero” decarbonisation push. Joining the board is Sigrid Kaag, a former Dutch finance minister with deep experience in trade, finance and sustainability. Her appointment is still subject to regulatory approvals.

On its own, one board change is not a red flag. What investors should note is the bigger pattern: Fortescue has seen heavy senior turnover under founder and executive chairman Andrew Forrest. That history is worth watching, as frequent changes at the top can make long-term strategy harder to judge. For now, though, Kaag’s background suggests continuity rather than a change of direction.

Real Zero Strategy Gathers Pace With 690MW Solar Push

The bigger news may be on the ground in the Pilbara. Fortescue has begun construction of a 690MW solar farm at Turner River, alongside a 650MWh battery at Cloudbreak. It is the largest solar project in Western Australia and a key part of the company’s plan to power its mines with renewable energy. Fortescue also expects its first battery-electric haul truck to be running before the end of the year.

The point of all this is “Real Zero”: cutting all direct emissions from its Australian iron ore operations by 2030, without buying carbon offsets. The plan is expensive, with a decarbonisation budget of roughly US$6.2 billion. But it is not only a cost story. Fortescue estimates that swapping diesel for electric power could save as much as US$400 million a year in fuel, a figure that looks more attractive every time global oil prices spike. We believe this is best seen as a long-term cost saver funded by today’s iron ore cash flow, rather than a drag on returns.

Is FMG a Buy?

Here is the key thing for investors: despite all the green energy headlines, Fortescue’s share price still moves with iron ore. FY25 showed why. Net profit fell 41% to US$3.4 billion as iron ore prices weakened, even though the company shipped a record 198.4 million tonnes and kept costs low. The full-year dividend was cut to A$1.10 per share, leaving a trailing yield of around 5.6% at the current share price.

At around A$21.82, FMG looks fairly priced rather than cheap. The balance sheet is solid, with about US$4.3 billion in cash and modest net debt. For income-focused investors, the dividend remains attractive, but it will rise and fall with iron ore. We think FMG suits patient investors comfortable with commodity swings, while those wanting a clear discount may prefer to wait for a weaker iron ore patch.
